It is not just ocean acidification. There is pollution, micro-plastic
pollution, over-fishing, warming temperatures, no-oxygen dead areas.

In the 1970s, when Earle last dove in the Coral Sea, she fell in love
with its vibrant reef, idyllic in its remote location far off the
northeast Australia coast.
"The whole point of going there was to find a really healthy,
beautiful system to come to the end of this film, and we can go:
'ta-dah, there's reason for hope,'" Earle told Co.Exist in an
